Strain sensing device and electric actuator having the same

Abstract

A strain sensing device includes a load body, a pair of strain gauges, and a cable connector. The load body has a chamber, an opening, and a mounting cover. The chamber is communicated to outside of the load body through the opening. A pair of detection surfaces are arranged on opposite sides of the chamber. The opening and the mounting cover are located on opposite sides of the chamber. The cable connector includes a connector head arranged on the mounting cover, and a cable threading the connector head and electrically connected to the strain gauges. When the load body is affected by an external force, the strain gauges respectively detect a deformation of the detection surfaces. The strain sensing device is therefore using alone as a load cell or in conjunction with an actuator and easily installing, disassembling and connecting an external wire.
